upgrading a 3500lb trailer axle?

i have a 6x12 trailer with a single 3500lb axle, leaf springs, and st205/75/r15 tires.
what is generally the weak link in this setup? i'd like to upgrade it to hold an occasional slightly heavier load.

could be anything. axle rating is pretty common, after that, maybe the hitch, various points of the frame depending on the design & materials used.

and don't forget, depending on jurisdiction, you may need to add brakes to the trailer if it doesn't already have them.

coupler is 5000lb rated. my main concern is the axle.

Everything, sell it and buy the correct size trailer. And no I am not just being a smart ***. The axle is undersized, watch some overloaded trailers going down the road and see how they have negative camber. Then there is the coupler and it's rating, should be stamped on it, but..... The springs, I shattered a bearing from fatigued springs 1000 miles from home, the same would be true of undersized springs. But the bigger problem is the frame, you really don't know what you have other that it is rated for what the trailer says.

trailer is fairly new and a 6x12, and most trailers in this size are single axle 3500lb. i dont want a larger trailer.
just looking to beef up a little. tires can go to 4500lb. so i'd be happy with that.

gonna maybe add bumstops at least, so axle wont hit frame.
looks like i have a lippert 3500lb axle.

you could add another 3500 lb axle. or you could swap axle with 5200lb rating.

A 5200 lb axle and matching leaf springs and heavier tires would take care of that issue, brakes are also needed for safety, then distributing your load so as not to stress the frame. I have a stock trailer I built in 1994 that has two 3500 lb axles with brakes. I have run it overloaded many times and run heavy duty tires and springs and keep the bearings in good conditions. Weigh the trailer with a load in it and see what your actual axle weight is as well as the tongue weight. Keep the tongue weight between 10 and 15% of total trailer weight.
